Recorder's Norwalk headquarters received a bomb threat on Saturday — the latest in a string of threats targeting election hubs across the region and country.

Authorities said the voter registration offices of Orange and Riverside counties were closed Friday after receiving a bomb threat.

The bomb threat was “communicated to” the registrar’s main facility on Berger Drive in North San Jose about 8 a.m. Saturday, leading to the evacuation of the building. Vote counting was suspended until the building can be cleared, according to the report.
